The loss-on-ignition (LOI) of PFA up to 8.0% was found to have a negligible effect. The results of strength development tests show that PFA fineness has an influence on strength, with a gradual reduction with decreasing fineness, as percentage retained on a 45-μm sieve. In particular, strength development and the durability of concrete that follows the guidance in BS 5328: Part 1: 1991, were studied. This paper describes a study carried out on the use of PFA to BS EN 450: 1995 as a binder component in concrete.
